Xport Interface: stylesheet::operator <<

Inserts a stylesheet item into a stylesheet.

stylesheet& stylesheet::operator << (
  const_stylesheet_item& item
);

Parameters

item

A stylesheet_item object, which can be one of the following derived objects: stylesheet_rule, stylesheet_import, or stylesheet_comment.

Returns

Returns a reference to the stylesheet object. Thus, this operation can be chained for multiple insertions.

Remarks

This operation offers an alternate method for inserting stylesheet items into a stylesheet. Although this method doesn't return an iterator like the insert() operation, it does allow the chaining of insertions, which the insert() operation does not. With this operation, the inserted item is inserted at the end of the stylesheet.

Complexity

Logarithmic

Example

#include "xhtml_doc.h"
#include <iostream>

int main(int argc, char* argv[])
{
  using namespace Xport;

  stylesheet ss;

  // insert a few rules
  ss  << stylesheet_comment("Sample stylesheet\n-----------------------------")
      << (stylesheet_rule("h1") << declaration(css::color, "red") << declaration(text_align, "center"))
      << (stylesheet_rule("p") << declaration(padding_left, "5px") << declaration(margin_top, "10px"))
      << (stylesheet_rule("#footer") << declaration(css::height, "50px") << declaration(css::border, "thin solid green"));

  // write the stylesheet to cout
  stylesheet_formatter fmtr(std::cout);
  fmtr << ss;
}
